- Available audio settings

The following Audio Setting menu options vary depending on the model of the Bluesound Player:

AUDIO SETTING	DESCRIPTION
Audio clock trim	Enable to reduce jitter and increase audio clock timing precision when using an external DAC. Note: Not all DACs can handle this. If audible clippings or dropouts occur, disable Audio Clock Trim to avoid BluOS's accuracy setting from interfering with the external DAC's firmware.
Balance	Adjust to balance audio volume on the left and right channels.
Bass	Adjust the Bass output levels of your Player.
Boost	Enable to add additional bass when you pair a Subwoofer.
Crossover	Adjust the crossover between 40Hz and 200Hz – by default, set to 80Hz. When the Subwoofer option is enabled, everything above the crossover is filtered out and sent to the RCA and Speaker Outputs. The Player sends anything below the set crossover out of the Subwoofer (SUBW) OUT.
Deep Bass	Enable to add additional bass to your listening experience when you do not connect a Subwoofer to the Bluesound Player. If you pair a Subwoofer, enable Boost to add extra bass.
Enhanced Dialog	Change this setting to Low or High to increase the volume of the center channel. The center channel broadcasts dialog in movie soundtracks and television.
Front Row	Enable to create a custom-tailored filter that provides a listening experience similar to being seated in a front row of live music performances. Enabling Front Row also disables other audio settings. For more information, refer to the Help Center article.
Late Night	Enable to turn on the Dynamic Range Compression that prevents large spikes in volume when streaming audio. (Ideal for small areas such as apartments or condos)
Listening Mode (Off/Music/Movie/Late Night)	Adjust settings within these listening modes to create separate listening profiles for Off, Music, Movie, and Night – that you can select to enjoy different listening experiences quickly. After configuring these Listening modes, you can change them directly from the Player Drawer in the BluOS Controller App or program an IR remote to select different listening modes.
Listening Mode (TV/Music/Movie)	Adjust settings within these listening modes to create separate listening profiles for TV, Music, and Movies – that you can select to enjoy different listening experiences quickly. After configuring these Listening modes, you can change them directly from the Player Drawer in the BluOS Controller App or program an IR remote to select different listening modes.
MQA external DAC	Enable this option when you require an MQA-certified external DAC to handle MQA unfolding rather than the Bluesound Player. Note: To enable MQA external DAC, you should enable the Output level fixed and disable – Tone Controls and Replay-gain. Learn more.
Output level fixed	Enable to fix the volume of the Bluesound Player at the maximum level. It helps when you control volume using the external device connected to the Bluesound Player instead of the BluOS Controller App.
Output mode	Select any of the following to configure the channel output on the Bluesound Player: Left/Right – Outputs only the Left or Right audio channel. Mono – Outputs single-channel audio out. Stereo – Outputs both Left and Right audio channels.
Replay-gain	Select any of the following to configure consistent volume levels between tracks in the play queue: Track gain– To use the track gain value from the song's metadata to have the current track's volume be more consistent with other tracks. Album gain – To use the album gain value from the metadata to provide a consistent volume level between all audio tracks on a particular album. Smart gain– To allow the BluOS to automatically choose between track gain and album gain values to provide the best replay gain option for your current listening. BluOS uses the metadata of the selected audio track to configure consistent volume levels between tracks.
Reset All	Restore the audio settings of the selected Player or Listening Mode to the default factory settings.
Select attached speakers	Select any of the following to configure the Speaker/Subwoofer setup connected to the Player: Bluesound Duo– Select to load custom EQ curve for perfect audio reproduction when connecting to Bluesound Duo. Other (no Subwoofer) – Select to send full-range audio to the connected speakers. The Player still sends audio frequencies less than 80 Hz through the SUBW (Subwoofer) OUT connector. Both the Subwoofer and speakers play the low-end bass. Other (with Subwoofer) – Select to send audio output less than 80Hz (default) to SUBW (Subwoofer) OUT only, increasing the audio performance of the speakers.
Stereo Surround	Enable to mix two-channel sources into the rear surrounds of a home theater group, generating an immersive and natural-sounding surround experience.
Subwoofer	Select any of the following to configure the Subwoofer setting: ON – Apply a high pass filter to the RCA and Speaker Out (where applicable) based on the crossover set. OFF – Send full range out of the RCA and Speaker Outs. Note that the SUBW OUT output will not be affected by this, nor will it set a filter on the digital outputs (applicable to NODE and VAULT only) When you pair a PULSE SUB+ with a PULSE SOUNDBAR, selecting Subwoofer displays the PULSE SUB+ Audio Settings.
Subwoofer Delay	Enable to add additional audio delay to a Subwoofer.
Subwoofer Volume	Adjust the volume of the connected Subwoofer relative to the PULSE SOUNDBAR's volume by +/-6dB.
Surround Upmixer	Enable to change channel-based audio (from 2-channel till 7.1) into a virtualized surround sound environment. Enable for Stereo Surround in a Home Theater Group.
Tone Controls	Enable to adjust your Player's Treble and Bass output levels. Notes: When enabled, the total volume of your Player is reduced by 6dB to allow adjustment of the bass and treble outputs from -6dB to 6dB. Tone Controls for the PULSE models are, by default, enabled. Tone Controls is disabled and not displayed when MQA external DAC is enabled.
Treble	Adjust the treble output levels of your Player.
Virtualizer	Enable to virtually experience Dolby Atmos content. Use this option to expand the audio soundstage of any source. Enable along with Surround Upmixer for the widest soundstage with a stereo source.
Volume Leveler	Enable to maintain consistent playback volume levels regardless of the source selection or content.
Volume limits	Set the upper and lower limit of volume controls in the BluOS Controller App. Modifying the upper or lower volume limits of the Bluesound Player allows more fidelity when adjusting the volume.
Wide Mode	Adjust the Bluesound Player's audio output to add depth and match the viewing/listening area in three selectable modes – Off, Wide, and Wider.
